Commit 21cbb6fe ("unistd.h: put getppid under XOPEN2K8") introduced a
new __THROWNL specification for non-leaf throws. It also made use of
these in the setjmp.h header. The functions that use this specification
(longjmp and siglongjmp) have their extern __libc__* equivalent
definition prototype specified using __typeof__ for the internal
function signatures. For C++ this copies the throw() specifier, since
this is part of the type for C++. The attribute in C is not.
This commit explicitly types out the signature for the two functions to
be compatible between the C++ and C worlds.
An alternative would be to keep the __typeof__ declaration and use
the copy attribute. Then the __THROWNL part could be thrown out since
the C attribute would be copied and the C++ exception specifier would
be part of the signature from __type__. However, since the copy
attribute is not supported for all compilers supported by uclibc-ng
this is not viable at this time.

Fix the [-Warray-parameter=] warning for __sigsetjmp generated by GCC 11 and
later GCC versions:
|
| warning: argument 1 of type 'struct __jmp_buf_tag *' declared as a pointer [-Warray-parameter=]
| extern int __sigsetjmp (struct __jmp_buf_tag *__env, int __savemask) __THROWNL;
| ...
| note: previously declared as an array 'struct __jmp_buf_tag[1]'
| extern int __sigsetjmp (struct __jmp_buf_tag __env[1], int __savemask)
|
Use the same fix as in glibc. The fix is to move the struct __jmp_buf_tag
definition to a separate bits/ header so it can be included in
pthread.h, to allow to use an array (as in setjmp.h) rather than a pointer
in the declaration.

This matches a similar change made to glibc.
No functional changes here.

Provide common prototypes for __longjmp, __libc_longjmp, __libc_siglongjmp
_longjmp_unwind, __libc_unwind_longjmp in setjmp.h in preparation for use in LT new
Add __longjmp to h8300 and i960
Make common longjmp.c good for NPTL
Guard _longjmp_unwind use in sh's longjmp.c for NPTL (I think sh could use the common one)
Remove unneeded attribute_noreturn, prototype provides it already
